To all whom it may concern.

Be it known that I, GEORGE L. HIBBARD, a citizen of the United States, residing at Grand Junction, in the county of Mesa and State of Colorado, have invented certain new and useful Improvements in Molds, of which the following is a speciication,. reference being hadto the accompanying draw- 1n s.

gIhis invention relates to an .improved mold for molding cement walls and like structures, andthe invention has for its primary object the provision of a mold of very simple construction, the various parts of which may be easily and quickly assembled andrigidly held in position to receive the cementitious material.

A further object of my invention is to provide a mold consisting of side and end plates, and means for easily and quickly' connecting said plates at the corners of the mold.

Another object of the invention is to provide a verystrong and durable mold which maybe constructed at low cost, the same consisting of a plurality of plates and wires connecting said plates and extending through the same, means mounted upon the mold plates to rigidly clamp the Wires thereto and hold the plates in their proper relative positions.

Still another object of the Ainvention resides in the provision of a mold for build ing a concrete wall to any desired-height., said mold consisting of removable side plates and wires connecting the same, said wires remaining in the wall and projecting from the faces thereof When'the plates are removed, and supporting elements adapted to4 be arranged upon the sides of the wall and rigidly secured-to the projecting ends of the Wires to support the mold plates upon the Vupper edge of the completed wall section.

With the above and other objects in lView., the invention consists of the novel fea-tures of construction, combination and arrangeplates acting as restraining walls; Fig. 3 illustrates the manner in which one of the mold plates may be used for building a concrete wall against a wall or other` foundation already 1n place; Fig. 4 is a perspective view of two opposed mold sections assembled in their relative positions, disclosing the arrangement of the square spreader bars or spacers which maintain said sections gainst the tension of the connecting Wires; ig. 5 is an enlarged detail section through one of the mold plates showing Athe means for clamping the wires in position; Fig. 6 1s an enlarged detail side elevation of the outer `mold plate, showing the means for tperating the Wire clamps; Fig. 7 is a section taken on the line 7 7 of Fi 6; Fig. 8 'is a fragmentary side elevation o one of the inside corners of the mold illustrating the means for connecting the side and end plates; Fig. 9 is a detail sectionof one cornei' of the' mold; Fig. 10 is a section similar crete wall; and Fig. 12 is a side elevation lates showing a modithe clamp operating of one .of the mold fied construction o means.

Referring in detail to the drawings 5 designates `two side plates o f the mold which are of similar form. Upon one face of each of the mo-ld plates 5 a plurality of longitu dinally disposed angle bars 6 are bolted, riveted or otherwise rigidly secured. Any preferred number of such angle bars may be employed, but it is desirable that oneof said bars be located ad'acent to each of ,the longitudinal edges of t e plate. The mold plates 5 and the ange of the angle bars which are secured thereto are provided with alined openings 7 and 8 respectivelyV through which the ends of the connecting wi.es 9 extend. These bars are adapted to be rigidly clamped at their ends upon the angle bars 6 by means of the cam levers 10 11 which are rigidly lixed said angle bars. Upon the inside mold plates as shown in Fig. 1, these 'cam levers `are horizontally disposed while on the'ou'tside -mold platesl they are vertically arranged, being` mounted upon the vertical flanges of the angle bars which are secured to the mold plates. As shown in the drawings, the ends of two of the connect-ing wires extend through each of the openings in the mold plates, and upon the inside plate a cam lever-10 is arranged for clamping engagement upon each of said wires while on the outside plate where the levers are vertically arranged, one lever engages the ends of both wires and clamps the same rigidly upon the horizontal flange of the angle bar. The cam port-ions 12 of, said clamping levers may be readily moved into engagement upon the wires by simply depressing said levers or forcing the same inwardly toward .the mld plate as shown in Fig. 4. In this manner the plates 5 of the mold are rigidly heldand supported in their adjusted positions. The connecting wires between said plates may be arranged in Amany different ways, some of which are illustrated in the accompanying drawings. In Fig. 1 for instance, there is shown transverse upper and lower wires and diagonally extending crossed wires.

The manner in which my improved mold is adapted to be used is illustrated in Figs. 1 to 3- of the drawings, though it will be understood that the device is also applicable to a great many other uses the illustration of which is not essential or necessary to a full understanding of the construction of the invention. In Fig. 1 the mold plates 5 are shown in their proper relative positions for forming the anchoring base or foot of the -wall to be molded. In this arrange-g ment of the plates it will be noted that the vangle bars 6 are disposed upon the 'outer faces of the plates. After the plates have been thus arranged the cement or other plastic material is poured between the same and allowed to set or harden to a sulicient degree so that it will retain its molded form when the plates are removed. The clamping levers 10 are then released from engagement with the wires 9 so thatthe plates may be removed and positioned forforming the remainder of the wall as will be later set forth. The clamping leversA on the upper and lower angle bars of theoutside mold plate are also adapted to be simultaneously operated to release the wires as will be fully disclosed from the following description.

- In Fig. 2 of the drawings the mold, plates reo are shown arranged for building a wall in quicksand or other material which is liable to cave, the mold plates acting as sustaining walls. It will be observed that in this use of the device the angle bars 6 which are secured to the mold plates are Adisposed inlwardly or in opposed relation, said plates being'reversedfrom the position shown 1n Figyl. In the arrangement of the vplates as shown in Fig. 2, transverse bars or spreadpers 14 are arranged between the mold plates at each end and at their upper and lower edges above and below the connecting wires 9 s o as to` retain them in proper position after being adjusted. In Fig. 2 the spreaders14 are arranged at their ends upon the opposed angle bars 6 and when the plates have been thus arranged, the plastic material is poured between'the same to the level of the lowermost angle bars. The mold plates are then drawn upwardly and more material is poured between the same until it ,again reaches the level of these lower angle bars.` ,In this manner a smooth unbroken surface of the finished structure is iobtained. Suitable chains 13 are connected to the upper edges of the mold plates whereby they` are elevated as the material is poured into the mold. In Fig. 3 I have shown the manner in which a cement wall may be constructed by means of my device along side of a wall or other foundation which is already in place. In such an instance, only one of the mold plates 5 is used. A bar or plate 15 is vertically disposed against one face of the permanent wall and is driven into the soil beneath the base of said wall, the upper end of the plate being suitably fixed tothe wall. The outer face of the plate 15 is perfectly smooth to form one side of the wall to be molded. One of my improved mold plates 5 is then arranged in opposed relation to the plate 15 andis connectedthereto by means of the wires 9. In this use of the device, I have illustrated the mold plate 5 set at an angle with relation to the plate 15 so that one side of the completed structure may be disposed at an inclination. The clamping levers 10 which are arranged upon the outer mold plates are connected by means of a common operating rod 16 which is rovided with a plurality. of short longitudlnal slots 17 to receive the studs 18 fixed in the ends of the cam levers 10. 'Wing nuts 19 are threaded upon said studs to retain the operating lever" thereon. The operating rod .the outsidevmold plate may be easily and quickly removed by releasing the same from the ends of the connecting wires 9.

l plates having offset In Fig. 12 I have illustrated a slightly -modifled form of this operating means which a plate 22 is riveted, said plate being co-extens1ve in height with the corner strip. To the end late of the mold upon its inner face a plur ity of plates 23 are riveted, said portions 24 disposedin spaced relatlon to the mold plate and in these .spaces the projectin portion 'of the plate 22 is adapted to be tted, the edge of the corner strip 21 abutting closel against the edge of the end plate of t e mold. Plates 23 are also secured to the corner strip 21 adjacent to its other longitudinal edge, while the plate 22 is secured to the side plate of the mold and extends beyond its vertical edge for arrangement between the offset portion 24 of the plate 23 and the outer face of the corner strip 2l. To the corner strip adjacent to each of its edges the resilient lates 25 are ixed at one of their ends, said plates carr ing pins 26 for engagement through aline openings 27 in the co-engaged connecting elements between the side and end plates and the corner strip.

It will be readily seen that the corner strips can be easily and quickly removed by simply pulling outwardly upon the spring plates 25 to remove the dowel pins from the openings. In Fig. 9 I have illustrated the manner of connectin the plates at the inside corners of the mo d whereby they may be vertically moved to disassemble the mold. This connection consists of substantially the same elements .as thoseemployed in the connection at the inside corners with the exception of the springs 25 and dowel pins 26. The same reference characters are also applied thereto.

In Fig. 11 of the drawings there is shown the manner of mounting and supporting the mold plates upon the upper edge of a completed wall section. For this purpose I employ a comparatively narrow plate 28 having an angle bar 29 secured thereto, said plate and bar having openings to receive the end portions of the wires 9 which are left in the wall section when the mold plates are removed. To the plate 28 at its upper edge a narrow metal strip 30 is secured having an oifset portion 3l to receive a plate 32 which is fixed to the lower edge of the mold plate. The upper longitudinal edges of the plate 28 and stri as the upper sur ace of the completed wall section. In this manner the mold plates may be easily andquickly arranged in position as each section of the 'wall is completed. Chains 33 are connected to the cam levers mounted upon the angle bar 29 and extend to the upper edge of the mold lates 5 to which they are removably attac ed in any desired manner. By means of these chains, the cam levers may be moved to disengage the same from the ends of the wires whereby the supporting plate 28 may be easily removed.

From the foregoing it is thought that the construction and manner of use of my improved Jmold will be readily understood without requiring 'any further description. The device is very simple, may be easily and quickly arranged in position and adjusted and is admirabl adapted for the building of concrete wa ls and other struc-y tures. Thedevice may also be manufactured at a very low cost and is extremely durable in practical use.

While I have shown and described theypreferred construction and arrangement of the various parts, and the more important uses to which the invention is primarily adapted, it will be understood that the device may also be utilized for various'analogous purposes and that its construction may be greatly modified from that disclosed in the foregoing description without departing from the essential feature or sacrificing any of the advantages of the invention.

Having thus described the invention what is claimed is 1. A mold of the character described includi spaced side plates, longitudinally extending angle bars secured upon the outer faces.of said side plates adjacent to their upper and lower edges and co-extensive in length therewith, the attached flanges of the angle bars and the plates having coinciding openings therein, transverse wires extending through said openings, additional transverse wires diagonally extending between said first named wires and having their extremities also disposed in said openings, spreader bars transversely extending between said side plates to maintain their spaced relation, and cam levers pivotally mounted upon the laterally disposed anges of the angle bars, said levers engaging respectively with the end of one of the irst named transverse wires and with one of the diagonally disposed wires to clamp the same agalnst the attached flanges of the angle bars and maintain the side plates in-their assembled positions.

2. A mold of the character described including spaced side plates, angle bars secured upon the outer faces of said side plates and in spaced relation to the upper 30 lie in the same plane4 and lower edges thereof, said angle bars being (fo-extensive in length with the plates,

the attached flanges of the bars and the plates having coinciding openings at their opposite ends, upper and lower transverse wires haring their extremities extended through said openings, crossed diagonal wires disposed in the vertical' plane of the transverse wires and between the same, the ends of said, diagonal wires being also disposed through said openings, cam levers arranged in pairs upon the laterally extending [langes ot' the angle bars and at opposite ends thereof, each pair of said levers being adapted to engage the end (if one of the'rst. 15

named wires and one of the diagonal Wifi/ies respectively and clamp the same against the attached [langes ofthe angle bars, and trans, e1-sel)v disposed spacing bars arranged bei:` tween the ends of said inold plates.
